I like magical materials, but something seems off using them to create hot springs.
So access to the correct substances essentially disables its physics-bending features, turning it into simply really hot stone. This heat would transfer to the local liquid, heating it. This would continue until the stone was out of latent heat and matched the water's temperature. Unless the water was subsequently removed, it would not gain any additional heat and everything would return to normal until the water left in some manner.
Now, if the algae were killed when the water got too hot, and began to grow when it cooled off again, then I could see a sustained cycle occurring, keeping the water at the desired temperature for the algae.
A good explanation of the demons of your world, though the first section is a little rough and needs to be reread.
Some is a little confusing:
Likewise, though the daimons will usually be a minor threat as they can't rejuvenate themselves in their home, some were originally powerful enough to be a significant threat in their time spent as a daimon.
So, even though they cannot recover from injury while on Atheus, they start off powerful enough to remain formidable for quite some time?
It would be interesting to see a king arise that held power not through his impotent army, and figurehead status, but through ties to the underworld. Blackmail, careful manoeuvring, intrigue. Keeping to the appearances of a lame duck, he would actually hold significant power. How the PC's play a role in this, perhaps they could give the impetus to change.
The Eclipse certainly makes this submission - the city as it was was a nice high-magic city, but not overly remarkable. The transformation into the war zone gives it a desperate air and like Gossamer said, having the PCs there when all hell breaks loose would make the greatest impact.
Well done! This would make a very interesting mini-campaign. Go to Comment
